DOI: 10.1021/acs.orglett.5c01410
Abstract: We report a straightforward synthesis of N-unsubstituted five-, six-, and seven-membered cyclic carbamates from amino alcohols and CO2, employing user-friendly propanephosphonic acid anhydride (T3P) as a dehydrating agent. Demanding substrates, such as amino alcohols bearing… read more here.
